Description

  The present invention relates to a snow fall prevention sheet on a vehicle roof provided in a vehicle such as an automobile or a passenger car so that snow on the roof does not fall on the windshield.

  If a car is left in an outdoor parking lot or the like in a snowy area in winter, it is often piled up to cover the car when it snows heavily or when the stop time is long. When driving in such a situation, since it is necessary to secure visibility, it is necessary to remove at least the snow accumulated on the windshield, so only the snow on the windshield is scraped off by hand or using a scraper. However, when there is not enough room, it is generally run with the snow on the roof remaining.

  However, if the brakes are suddenly applied to the vehicle while traveling to decelerate or stop, the snow on the roof slides down on the windshield and the field of view is interrupted, which may lead to a dangerous situation for driving. In particular, if a thin water film is formed between the roof and the snow due to the effect of room temperature, it will be slippery and a large amount of snow will flow down, causing damage to the front wiper due to the weight of the snow and the impact of the fall. There is also. In order to prevent such dangers and inconveniences, if the snow on the roof is also removed in advance, not only will it take time but also work will be difficult due to the high location.

Therefore, conventionally, as described in the following document, a snow fall prevention device adhered along the edge of the windshield so as not to fall on the windshield even if the snow on the roof is left as it is. According to this, it was a structure in which a support piece was disposed between both pieces having an L-shaped cross section.
Japanese Patent Laid-Open No. 03-186659

  According to the conventional snow fall prevention device as described above, a piece having an L-shaped cross section is adhered onto the roof, so that the other piece is kept standing. This prevents slipping and prevents falling onto the windshield. However, since it is easy to stagnate over the entire roof with the snow following the upright piece, the driving is disadvantageous in terms of fuel consumption of traveling with snow on the roof. In particular, if the supporting piece between the two pieces having an L-shaped cross section is frozen, there is a problem that the snow does not easily fall from the roof to the surroundings and is easily stagnated.

  Moreover, even if the snow cover on the roof is retracted, not only the snow is entangled with the support pieces to be arranged, but also the scraper is caught by it, making the removal work difficult. In addition, since the upright piece is a screen that receives wind resistance, this is not only disadvantageous for fuel consumption, but also when there is no snow, there is an unexpected situation where the wind resistance peels off and blows away. However, there is a problem in that it has to be firmly bonded so that it cannot be easily removed, and since it is strong, it cannot be removed after the winter season.

  In view of the above situation, the present invention not only prevents the snow from falling on the windshield even when driving with snow on the roof. Vehicles on the vehicle roof that can be easily attached by using easy-to-removable adhesive means because they can be scattered and disappear easily, and even if the snow on the roof is removed, there is no hindrance to the work and there is no wind resistance. The object was to provide a snow fall prevention sheet on the roof.

  In order to solve the above problems, the present invention is formed in a flexible plastic or semi-rigid plastic sheet shape so that it can be closely attached to the roof of the vehicle, and in the width direction long to the left and right on the upper surface where snow is accumulated In order to prevent snow from moving in the direction of the windshield of the car, the ridges and grooves are formed by alternately arranging front and rear ridges and grooves. The present invention provides a snow fall prevention sheet for a vehicle roof, characterized in that the attachment means is provided on the lower surface so as to be detachably attached to the vehicle roof.

Moreover, in the same structure (Claim 2), the snowfall fall prevention sheet | seat in the vehicle roof for cutting which can be cut and used for free magnitude | sizes and shapes is provided.
(Function)

  Since the snow fall prevention sheet on the vehicle roof is configured as described above, when the sheet is used, it is attached to the vehicle roof at least along the windshield. In this installed state, if there is snow while parking in the field, even if you remove only the snow on the windshield and drive, even if you decelerate or stop while driving, there is snow on the hanging surface of the ridge. Is prevented from falling onto the windshield. Also, when starting or accelerating, the flank allows the snow to slip, so the snow is swept away and gradually scattered from the rear end and the left and right.

  In addition, since it is not subjected to wind resistance, it is safe to peel off from the roof even if it is attached with an adhesive or a magnet, and it can be easily removed even after the period of use.

  As described above, according to the snow fall prevention sheet for a vehicle roof according to the present invention, it is possible to prevent the snow from falling on the windshield even when driving with snow on the roof, and to Since the snow is scattered and disappears from the left and right, safe driving can be secured conveniently and reasonably, and even if the snow on the roof is removed, there is no hindrance to the work, and it has a low sheet shape. Since it is not subject to wind resistance, it can be easily attached with easy-to-removable adhesive and adsorption means, not only is it convenient for removal after the period of use, and it is also advantageous for fuel consumption, There is an excellent effect that the appearance can be maintained without greatly affecting the appearance (form) of the vehicle, and on the contrary, the novelty can be given casually together with the functionality.

  Further, when it is used for carving, it can be provided at a low cost, and it is easy for the user to use it in an optimum state in relation to the vehicle or the like.

  Next, embodiments of the present invention will be described with reference to the drawings.

  1 to 5 show an embodiment, and the snow fall prevention sheet P on the vehicle roof is shown in FIGS. 3, 4 and 5 in the elliptical frame A of FIG. 2, and is soft or semi-rigid plastic. For example, it is formed in a generally rectangular sheet shape with vinyl chloride or urethane rubber, and horizontally long ridges 2, 2,... Are continuously formed on the upper surface, and adhesive 5 is applied to the back surface. On top of that, a release paper 7 made of a thin plastic sheet or paper is adhered.

  As for the shape of the upper surface of the seat, the ridges 2, 2,... Are inclined so that the front surface becomes the flank 8 and the rear surface rises so that the rear surface becomes the hooking surface 9. It has a shape, and there are grooves 3, 3,. Further, in the front end ridge 2, the flank 8 intersects the lower surface and the tip 11 is sharp, thus making it easy for the snow accumulation S to ride. Furthermore, the left and right ends are formed with inclined surfaces 13 that are low on the outside so that the snow accumulation S can easily escape.

  In addition, when the front end and the both side ends are sharp in this way, it is advantageous because it does not get caught when the scraper is used. Furthermore, since the thin piece 12 as an extension of the sheet base portion without the protrusion 2 protrudes at the rear end, when removing it when it is used, it can be easily peeled off from the roof R by turning over from the thin piece 12. . However, since it is at the rear end, the flakes 12 are not spontaneously (inadvertently) beaten due to the movement of snow, etc., and the adhesion to the snow fall prevention sheet P is given stability by being firmly fixed on the roof R. Will be.

  When the snow fall prevention sheet P is used, as shown in the oval frame A in FIG. 2, the release paper 7 is peeled off and the lower surface is adhered to the roof R of the automobile with the adhesive 5. In FIG. 1, they are arranged so that there are three rows horizontally and two rows before and after. This arrangement varies depending on the size, shape, and the like of the snow fall prevention sheet P in relation to the automobile.

  In any case, when the automobile T is decelerated or stopped while traveling, the snow S does not slip forward by being caught on the hanging surface 9 of the ridges 2, 2,. Thus, there is no inconvenience that the field of view suddenly disappears or the wiper 16 is broken. Further, when the vehicle starts or accelerates, the snow cover S moves backward by the flank 8 and gradually, every time, the snow cover S is gradually scattered on the road from behind the roof like an extrusion.

  Further, in the arrangement of FIG. 1, the snow fall prevention sheets P, P in the left and right side rows are arranged in an inclined arrangement with the outside slightly behind, so that when starting or accelerating, the inclined protrusions 2, 2 are inclined. The snow cover S moves to both sides of the automobile along the grooves 3, 3,... And the snow cover is also removed from both ends. The emphasis on this effect is in the case of the examples described later (FIG. 7). Moreover, if the above effect | action is fulfilled, the shape of the protrusion 2 (relatively the shape of the groove 3) will be various as follows.

  FIG. 6 illustrates another shape of the protrusion 2, and in FIG. 6A, the protrusion 2 has a trapezoidal shape with a flat upper surface 17 between the flank 8 and the hooking surface 9. The bottom surface 19 of the groove 3 is also formed flat. Further, in FIG. 2B, the protrusion 2 has a hooking surface 9 following the flank 8 formed on an arcuate round surface. Also in this case, the bottom surface 19 of the groove 3 is formed flat.

  As described above, FIG. 7 is an example in which the amount of snow on the roof S is increased to the left and right, and the width on the left and right is formed to be close to the width of the roof according to the embodiment. The ridges 2, 2,... And the grooves 3, 3,.

  Further, FIG. 8 shows that by forming the snow fall prevention sheet Pa widely, it is easy to devise so that the function of removing the snow cover S can be maximized according to the roof of the vehicle. By using scissors and scissors, it is used by separating them as appropriate. In other words, the arrangement shown in FIG. 1 can be made by cutting the size and shape freely, and the shape shown in FIG. 7 (in this case, the left and right halves are matched). ).

  In the above, the attachment means that is detachably fixed to the roof of the vehicle is based on the adhesive 5, but it can also be based on other means such as magnet adsorption. The snow fall prevention sheet P (Pa) shown in FIG. 9 shows an example in which a plastic (or rubber) sheet-like magnet 21 is bonded to the lower surface. FIG. 10 shows a case where the entire snow fall prevention sheet P (Pa) is formed with a plastic (or rubber) magnet 21. Plastic magnets and rubber magnets are made by kneading magnet powder into plastic or rubber. However, it is possible to be able to attract the roof with a normal magnet.

  In each of the embodiments described above, the snow fall prevention sheets P and Pa can prevent snow from moving in an inconspicuous thin and low shape, but can also be made into a transparent sheet or inconspicuous even in the same color as the vehicle T. . Conversely, it is also possible to decorate a vehicle and change it into a novel design in a unique shape and color.
